VIZIO P42 plasma, half screen ok, other half showing blank

I have Plasma Tv. My screen is split. One half shows the picture, the other half shows one green band. What could be the problem. I opened the TV , but nothing looks short. I am knowledgable to certain extent on chnaging boards. Any help would be apprecated? Could it be mother board or the screen drivers. The screen is split vertically. So left side is blank and right side has picture.

If you are familiar with using a DMM, the simplest way is to test each of the fuses mounted on each of the internal boards, which means that you will have to remove the back of the TV panel. Each fuse should not test open. If it does, you probably have a failed component/circuit on the board that the fuse is mounted on. UNPLUG THE TV BEFORE REMOVING THE BACK PANEL. Do not plug the TV in while you are testing the fuses. There are some seriously high voltages in the TV, plus there may be residual voltage from the large power electrolytic capacitors, so try not to touch anything and if you do, use just one hand with the other not touching anything.

First you have to check if voltage and data are ok at the Y sustain board and the Y driver boards are not running hot. Even if you know how to replace these panels you must have a scope to adjust the v-set up and v- down. Not just a simple PNP. Trouble shooting a plasma is not a short time process to do it correctly. Please let a service center look at it for you.

Try first unplugging power cable for thirty minutes, then plug back, this will drain power from TV completely and will reset it.

See if it works.

Hello Danyell,
According to the model number you provided you have a 42" Insignia plasma TV. The problem you reported with having just a blank black screen on the lower half is due to a bad lower buffer board or also called a lower scan board. The part number is LJ92-01739C and if you Google this part number you can find these online and also find some sites that may show a short video on how to replace it. Price of this board looks to be about $35. Also of note is you will find that this part number is a Samsung part number which means your Insignia TV has a Samsung plasma panel in it so the associated circuit boards will also be Samsung parts.

No video/picture


Solution is to get it fixed (hopefully under warranty).

I have the same issue after owning the Vizio 42" LCD for just 5 months. They are coming to replace the part this week. I will also be purchasing the extended warranty as well, to avoid this problem in the future.
